Abstract
La transformación catalítica de 5-hidroximetilfurfural (HMF) para producir 2,5-dimetilfurano
(DMF) se estudió sobre catalizadores bimetálicos (PtIr) y monometálicos (Pt) soportados en materiales
mesoporosos CMK-3 y SBA-15. La temperatura y presión óptimas para la producción máxima de DMF
fueron 120 ° y 15 atm. Los aumentos de temperatura y presión disminuyeron la selectividad a DMF.
Los catalizadores se caracterizaron ampliamente por XRD, N2-isotermas, XPS, TPR, TEM y NH3-TPD.
Los sitios activos de la aleación PtIr fueron muy activos y selectivos hacia la formación de la DMF
deseada. El catalizador PtIr-CMK-3 mostró una excelente actividad y selectividad.
The catalytic transformation of 5-hydroxymethylfurfural (HMF) to produce 2,5-dimethylfuran (DMF) was studied over bimetallic (PtIr) and monometallic (Pt) catalysts supported on CMK-3 and SBA-15 mesoporous materials. The optimum temperature and pressure for the maximum production of DMF were 120° and 15 atm. Increases in temperature and pressure decreased the selectivity to DMF. The catalysts were broadly characterized by XRD, N2-isotherms, XPS, TPR, TEM and NH3-TPD. The PtIr alloy species active sites were very active and selective towards the formation of the desired DMF. PtIr-CMK-3 showed an excellent activity, selectivity and stability to be applied in this process
